CONCRETE-MOLD.

To (/U 11 7mm it 711(1 1 coaerrrt:

Be it known that 1, 1101' N. NEIL, a citiI- en ol' the boiled States,and a resident; of tozad, in the county of Dawson and State. ofXehraslca, have invented a new and improved (oncrcie-Mold, of which thel'olloaing is a full, clear, and exact description.

My invention relates to concrete molds. and it has for its object toprovide one with side members which are connected by spools supported byrods disposed therein, the spools having hollow heads in which the rodsare screwed, there being also additional screw threads in receswes inthe. extremities of the heads in which nuts having orilices therein areadapted to mesh, there being means in the heads respectively to preventthe rotation of the heads on bolts which are disposed in the orifices inthe nuts respcctively. I also provide hollow cores to be disposedbetween the side members and the spools, the hollow cores and the spoolsbeing permitted to remain in the concrete alter the bolts are withdrawnand the side members are removed, but if desired the spools maybeWithdrawn it this is done at the proper time, the heads being firstunscrewed.

Still other objects of the invention will appear in the followingcomplete description.

In this specification I will describe the pre ferred form of myinvention, but it will be understood that I do not limit myselt' theretoas I consider myself entitled to all'l'orms and embodiments of theinvention which may pended claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures, in which Figure 1 is aperspective View showing my mold erected ready for concrete to bedistransverse sectional view of my invention; Fig. 3 is a plan View ofmy invention; Fig. 4 is a similar plan View but with hollow cores of adifferent shape disposed in the concrete; Fig. 5 is anenlargedfragmentary View show ing a spool, its head and the bolt by means of Iwhich 1t is hold to aside member; Fig. 6 is a similar view but showingcaps by which the spool heads are separated from the side memher, andFig. 7 is a similar view showing the spool with its head embedded in thecon- Specification of Letters Patent.

moved and a bolt and nut disposed in an oiilicc in the head ol' thespool, the out being screwed into the spool head and the head of thebolt being disposed in an angular recess i the head.

By referring to the drawings, it will be seen that side members] areprovided, which may be constructed olJmctal or other nmterial. though inthe drawings the side members are shown as constructed of metal withangle steel portions 2. at their edges, the'angle steel portions beingbolted to the side members to still'en them. Between the side members 1,which are. spaced apart, are disposed spools 3, having heads 4, bolts 5being disposed through the spools and heads, the bolts passing throughori'lices 6 in the side members 1 and through orilices 7 in angle.steels 8, which are bolted to the side members 1. 'lhc bolts 5 are heldin position by means ol nuts 9, which mesh with screw threads on thebolts and press :Wainst the angle steels S. The spools 3 are scrmvedinto theirheads 4, the heads raving threaded recesses l0 and angularrecesses 11 disposed inwardly from the threaded recesses 10. Thisconstruction isprovided, so that when the nuts 9 are removed and thebolts 5 are with drawn from the spools 3, a nut 11.? having an oriiice13, may be screwed into the recess 10 in the heads 4, and a bolt 1 1-.disposed in the oriiice 13, the head 15 of the bolt 14 being disposed inthe angular recess 11, to prevent the bolt 14 from rotating. By thisconstruction, it is possible to secure the concrete mold to othermembers, or to supports which will hold the concrete mold in apredetermined position. It is also possible to unscrew the heads 4 andremove the spools It;

provided this is done before theconcrctc has become too hard. When it isdesired to have a smooth surface of the concrete block, unbroken by thespool heads 4, caps is may be, disposed between the spool heads 1- andthe side member 1, so that when the nuts l) are removed and the bolts 5arc witlnlrawn, the caps 16 may also be removed and the spool heads 4may be covered by concrete mortar. Between the side members 1 aredisposed hollow core members 17, which may be annnlar in shape in crosssection, as shown in Fig. 3, or elliptical in shape, in cross section,as shown in Fig. t. when elliptical hollow cores 18 are used,1 prel'crtolap them as shown in Fig. 4, to all'ord additional strength, andadditional resistance to the passage of heat and moisture, the cores 18being spaced apart at intervals to permit the spools 8 to be disposedtherebetween. The angle steels 2 have orifices 19 therein, in which maybe disposed studs, the studs projecting into similar orifices 19 in anadjoining side member which is disposed in alinement or at an angle withthe first named side member, and which it is desired to retain in thisposition. Guides 20 project from the side members 1 near their top andbottom, the object of these guides 20 being to enable the side membersto be read justed after a mold has been formed, so that the lower guides20 may be disposed in the recesses formed by the upper guides 20, and inthis manner a concrete wall may be formed by degrees with the sidemembers disposed in the same plane, after they have been advanced to thenew position. Angle steels 21 are bolted to the inner faces of the sidemembers 1, the angle steels 21 being pro vided to support a smoothingmember 22. which is provided for smoothing the top of the concereteblock or wall at any predetermined height, the angle steels 21 being ad-'ustable on the sidemembers 1, as they are bolted to the side members 1and to the angle steels 8, the bolts passing through orifices In usingmy invention, the side members 1 are erected with the s ools 3 disposedtherebetween and with the olts 5 disposed in the spools. The nuts 9screw on the bolts to secure them firmly to the side members 1 and tothe angle steels 8. The angle steels 21 are then adjusted at the )roperheight, and are then bolted to the side members and to the angle steels8. Hollow cores of the desired shape are then disposed between the sidemembers 1, when the space between the side members 1, with the exception01' the openings in the cores, is filled with concrete tothe level ofthe angle steels 21, when the smoothing member 22 isdisposed on theangle steels and the upper surfaces of the mold is leveled. After themold is sulliciently hard the nuts 9 are unscrewed and the side members1 are removed, and the bolts 5 are withdrawn, leaving the spools 3 withtheir heads and the cores in the mold but if desired the heads beunscrewed and the spools may be withdrawn. The bolt 14 is then disposedin the orifice 13 in the nut 12, the head 15 of the bolt bein insertedin the angular recess 11 in the spool head 4 and the nut 12 beingscrewed in the threaded recess 10, the concrete block being adapted tobe supported by the bolts 14. When there is no necessity of using thebolts 14 to support the *oncrete bloc r, the caps 16 are provided toseparate the head 15 from the side member 1, and after the side member1, the cap 16 and the bolt 5 have been removed, the spool'head 4 iscovered with concrete mortar to make an even surface on the side of theconcrete block. As has been stated, when a wall of any ,height is to beconstructed, after the side members have been removed from the concretewall already formed, they are disposed so that their lower guides willrest in the recesses previously occupied by the upper 1 guides 20 on theside members, so that the same side members which are used to constructthe lower portion of the wall may be used to complete its upperconstruction.
